I've recently attempted to pull a 5596UP from storage to handle some extra load but was faced with an odd issue, I have zero console output. The status lights on both PSUs work, as well as the small red/green status indicator on the SFP+ side of the switch, but none of the fan module lights illuminate, the switch never boots and I have zero signs of life on both the management and console ports. It has no expansion modules installed either.
The only sign of life I do get is a blink on the ethernet status lights of the L1, L2 and MGMT port. It takes about a minute, they all come on at the same time for about a second, and then go off again. I really have no clue what is going on, AFAIK the switch was fully working when originally decommissioned. Is this likely a hardware issue? I have been unable to find any similar issues online. Happy to update with any extra info on request, no idea where to start with this.
Any help is appreciated, thanks!
